TOBACCO PIPE.

Application led November 1, 1923. Serial No. 672,170.

through, lsaid closure being removable so as to permit theV easycleaning of said passage when desired. Y

My invention has among its objects the production of a device of thekind described, which is simple, convenient, efficient and satisfactoryfor luse wherever found applicable.

Many other objects and advantages of the construction herein shown `anddescribed will be'obvious to those skilled in the art from thedisclosures herein given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularlyv pointed out in the claims.

In the drawings, wherein like reference charactersV indicate like orcorresponding parts: Y

Fig. 1 is a perspective view of my device;

Fig. 2 is a sectional view of the same;

Fig. 3 is an enlarged fragmentary section showing the end .closure forthe draftl passage; and

Fig. 4 is a sectional view taken substantially on line /1-4 of Fig. 3.

In the drawings, wherein I have illustrated the preferred embodiments ofmy invention, there is shown a pipe having a chambered bowl portion 1withl a stem 2 eX- tending therefrom. The stem may be made in yone ormore parts, there being two parts shown, and may be either integral withor separate from the bowl.

Extending clear through the stem and the bowl is a draft passage 3, thisdraft passage being continuous-from the free end of the stemto theexterior. of the bowl, and preferably being arranged so that it includesthe lower portion of the tobacco chamber.

The passage from the stem to the tobacco,

chamber is always open when the pipe is in use and I have arrangedk aclosure at the end of the passage through the bowl.

This closure preferably comprises a cupshaped member having an annularrim 4, a hub or seat 5 having a tapered exterior peripheral wall 6, aweb 'v connecting the hub and rim at one side of the rim, andv anannular outwardly directed flange v8 at the other end of the rim. Slits9 may be" formed through the rim at the flanged end, if desired, so asto render the rim slightly expansible thereat. The hub is yprovided witha bore 10 `therethrough of thesame size the passage-way 3 and inregistry therewith. Y K

A plng or cap having a head 11 is provided with a chamber 12 from oneend so as to form a neck portion 13 adapted to frictionally enter theopen end of the cup- 'i shaped member and form a closure therefor. Agasket or disk 14 is arranged in `the chamber 12, the free end of theneckportion 13 being ianged' or peened radially inwardly as at 15 to'preventthe gasket from falling out.` A spring or other -resilient member16 is interposed between the, gasket and the bottom wall 'of the recess12 to constantly urge the gasket outwardly of the recess and againstVthe hub `or seat 5 so as to form an effective seal for the draftpassage. The cup-shaped member is pressed into the bowl at the end ofthedraft passage and may be cemented there-at if desired, the cap beingremovably insertable thereinto. s

Thus it is seen that I have provided an effective `closure for the endof the draft passage and which will be eiiieient in operation, will notbecome easily lostor injured, andV which Will be relativelyinconspicuous when in place.

The stem 2 may be either straight or bent and in both cases theoperation of the device. When it is `desired to` will be the same. cleanthe passage, the cap is removed either by the finger or by any suitabletool, suoli as a knife, va coin or the like, and a pipe cleaner isinserted through the stem yand finally drawn outwardly of the passagefrom the closure end. Thus there is no danger of the nicotine beingdrawn up into the mouthpiece when removing the cleaner. -The closure maybe fitted to either old pipes ornew ones, as desired. It will be notedthat I so form the parts in the preferred construction that thefingernail or tool may be so pushed in thespace 20, that thecap will beforced off without pulling. This makes itmore easy to bemoved with thenail and without danger of splitting the linger or thumb nail.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made m the same without departing 'fromthe spirit of my invention; hence I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination ot parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

\l. A tobacco pipe, comprising a chambered bowl and a stem provided witha draft passage therethrough extending to the exterior o' said bowl, andyieldable means closing said passage at the exterior oi? said bowl.

2. A tobacco pipe, comprising a chambered bowl and a stem provided witha draft passage therethrough extending to the exterior ot said bowl, acup-shaped member inserted into said bowl at the end or" said passage, acap frictionally insertable into said cup-shaped member to form a cies:therefor, and a compressible gasket between said cup-shaped memberandcap.

3. A tobacco pipe having abowl and a steni provided with a passageextending thr ugh vthe stern to the exterior of said bowl, a memberinserted in said bowl at the end oit' said passage andhaving a bore inline therewith, a removable cap rictionally slidable into the end otsaid member to form a closure therefor, a disk movably held in said cap,and resilient means between said disk and cap to press the disk againstthe bore through said member.

4. A tobacco pipe, comprising a chambered bowl and a stem provided witha draft passage therethrough, a metal member insertedy into the end ofsaid passage and comprising a rim portion, a bored hub and a webconnecting said hub andv web connecting said hub and rim, and a caphaving a neck portion frictionally insertable linto said member betweenthe inner wall oi the rim and the outer wall of the hub, a gasketmovably held in said neck, and a spring between said gasket and cap topress said gasket against the end of said hub to seal passagetherethrough.

5. A tobacco pipe, comprising a chambered bowl and a stem provided witha draft passage therethrough extending to the ex terior of the bowl, acup-shaped member inserted into said bowl at the end of said passage,and comprising an annular rim portion having an outwardly directed endflange at one side, a web across the other side, a hub the center ofsaid web transverse thereto and having a tapered exterior surface, and acap having a chamber therein from one end to form a neck portion to frictionally engage the inner surface of said rim, the tree end o1L saidneck portion adapted to encircle said tapered hub, a coinpressiblegasket within the chamber of the cap, a spring in said chamber andbearing on said gasket to press it against the bore through said hub,the outer end of said cupshaped vmember having slits therethrough so asto render it radially expansible thereat.

6. A tobacco pipe comprising a chambered bowl and a stem provided with adraft passage` therethrough extending to the eX- terior of the bowl,a-cornpressible gasket inserted into said bowl at the end ot saidpassage, and means for holding the gasket in place in the passage.

7. A tobacco pipe comprising a chambered bowl and a stem provided with adraft passage therethrough extending to the eX- terior of the bowl, acompressible gasket inserted into said bowl at the end ot' said passage,and yielding means for holdingV the gasket in place in the passage.

ln testimony whereof, i, have hereunto signed my name in the presence oftwo subscribing witnesses.
